VENTILATOR SASH.

Specification of Letters Patent.

Patented Mar. 7, 1922.

Application filed April 19, 1920. Serial No. 374,984.

To all whom it may concern:

Be it known that I, CHanLns L. TLXRRISON, a citizen of the United States-and residing at Richmond, in the county of Henrico and State oi Virginia, have invented a new and useful Ventilator Sash, of which the following is a specification.

The object of my invention is to provide an improved ventilator sash especially adapted for use in car windows and adapted to permit of convenient regulation of the ventilation by the passenger and the convenient detachment and removal or the screen should it be necessary to replace same; to provide an improved arrangement oi the ventilator door with the knobs projecting but slightly beyond the surface of the sash, to provide an improved screen; and improved means for mounting and removing same.

I attain the object of my invention by the mechanism illustrated in the accompanying drawings, in which Figure 1 is a front elevation of the invention applied to the window of a dining car; Fig. 2 is a vertical section oi the device;

Fig. is a section on the line 33 of: Fig. 2;

Fig. 4 is a rear elevation of the invention vieweditrom outside the car;

Fig. 5 is a horizontal section on line 5-5 oil Fig. 2; and i Fig. 6 is a detailed perspective view of one end of the screen and cinder guard.

Like numerals designate like parts in each of the several views.

Referring to the accompanying; drawings I provide a ventilator sash 1 having a cross rail 2 on the rear side of which is mounted the ventilator door 3 horizontally secured to the cross rail 2 by hinges 16. Door 3 when closed abuts against the ornamental edge strips 23 of the ventilator opening. The bottom sash forms the inner ventilator wall 4, the upper edge of which projects past the bottom edge of the outer detachable ventilator wall 7. Member 4 is provided with a suitable heavy rubber weather strip as shown in Fig. 2. The top of the ventilator is closed by the cover 8, shaped as shown in Fig. 2 and having its upper edge secured to the erosss rail 2 by suitable screws 22 and having its lower inwardly bent portion 21 engaging the upper edge of the outer ventilator wall 7.. The outer ventilator wall '7 is detachably secured to side walls 6 by suitable screws 20, which permit of easy removal of wall 7. Wall 7 is provided with a suitable screen-supporting ledge 10. Screen 11 is removably mounted on ledges 10 and 9, it being possible to readily detach it when wall 7 has been detached. The side walls 6 are suitably secured to the sash as by screws 24. My improved form of screen consists of the screen 11 mounted in metal side screen frames 13 and end screen frames 12. It is provided with a guard strip 1d extending at right angles to the main portion of the screen. I provide cinder guards 15 formed integrally with or rigidly secured to the frame of the screen and positioned at either end, substantially as shown in Fig. 6. Guard strip or extension 14 is preferably formed integral with or is an extension of wall 7 and supports the screen frame 13, as illustrated in Fig. 2, and frame 13 is provided with a depending securing flange or strip 26, as shown in Figs. 2 and 6. Secured to side walls 6 I provide flat end springs 18 adapted to frictionally engage the ends 19 or ventilator door 3 to adjustably hold. same in its adjusted position. I provide horizontal slots 25 in side walls 6 to receive the ends of screen 11. j

I As the ventilator door 3 is hinged to the inner side of the cross rail 2' and is of less thickness than that member, the knob 17 is prevented from projecting to any more than a slight extent beyond the outer faces of members 2 and a. The springs 18 friction ally engage the edges of the door 3 and hold it in position tojwhich it has been adjusted. It will be observed that I have provided means for permitting of the convenient removal and replacement of screen 11 when desired. When desired to effect its removal screws 20 are withdrawn and outer ventilator wall 7 is removed, thus permitting the screen. 11 with its attached cinder guards 15 to be withdrawn.

By the disposition of ventilator door 3 illustrated in the drawings, set in from the faces of members 2 and 4: I provide a construction that is mechanically more efiicient because of the disposition of knob 17 and which also is much more ornamental in appearance.

The term screen is used by me as intended to designate any suitable screen member adapted to close the ventilator opening, whether or not the particular preferred frame disclosed herein is used with the screen.

What I claim is: i

1. In a device of the class described, the combination with a. ventilator sash of a ventilator door vertically hinged to the inner side of the cross rail of the sash and adapted to close the ventilator opening, said door opening inwardly and being disposed in a recessed position relative to the face of the sash, whereby the knobs carried by the ventilator door are prevented from project ing to an undersirable extent.

2. In combination with a ventilator having a swinging ventilator door, single flat springs mounted on the side walls of the ventilator adjacent the door and resiliently engaging the edges of the door whereby to hold same in any desired adjusted position.

3. As a new article of manufacture for use in a ventilator of the type described, a combined screen and cinder guard comprising a screen, a frame in which said screen is mounted, cinder guard members formed integrally with the frame transversely at either end thereof and depending diagonally therefrom, and a guard strip extending longitudinally along one side of the frame at right angles thereto.

4. In a ventilator sash the combination of a window having a ventilator combined therewith, the lower edge of the sash constituting the lower inner wall. of the ventilator, a cross rail spaced above the bottom of the sash, a swinging ventilator door hingedly mountedto the inner side of the cross rail, the ventilator door being of less thick-V ness than the cross rail, resilient means on either side ofthe ventilator door frictionally engaging same to hold the door in adjusted position, adetachable ventilator cover, an outer detachable ventilator wall having its upper edge in contact with the lower portion of the cover, and having its lower edge proj ecting past the upper edge of the lower sash member which constitutes the inner wall of the ventilator, the lower portion of the aforecinder guard, a screen supporting element mounted on the outer ventilator wall, the side walls of the ventilator being slotted, and a screen removably mounted in the slotted side walls.

5. A ventilator sash having the ventilator mounted on and forming the bottom portion of the sash, and comprising side walls secured to the sash, a cover for the ventilator, spaced ventilating walls having their free edges projecting past the same. horizontal plane, the side walls having horizontal slots therein, a screen removably mounted in the slots in the walls of the ventilator, a swing ing ventilator door and resilient means for holding said ventilator door in adjusted position.

6. In a ventilator sash, the combination of a window having a ventilator combined therewith, the'lower edge of the sash constituting the lower inner wall of the ventilator, side walls secured to the sash, a cross rail spaced above the bottom of the sash, a

swinging ventilator door hingedly mounted to the inner slde of the cross rall, the vent1- lator door being 01 less thickness than the cross rail, resilient means on either side of the ventilator door frictionally engaging same to hold the door in adjusted position, a detachable ventilator cover, an outer detachable ventilator wall having its upper edge in contact with the lower portion of the cover, and having 'itslower edge proj ecting past the upper edge of the lower sash member which constitutes the inner'wall of the ventilator, the lower portion of the aforesaid detachable wall projecting below the screen and functioning as a cinder guard, a screen supporting element mounted on the outer ventilatorwall, the side walls of the ventilator being slotted, and a screen removably mounted in the slotted side walls, and a weather strip extending longitudinally of the screen member and adapted to be secured to the ventilator sash to firmly secure the screen in position attached to the sash, substantially as shown.

CHARLES L. HARRISON.
